Thread: Clear Screen Code

Can someone please explain this function? I found it in one of the threads on this forum, but I can't decipher it.

Code:

void clrscr()
{
   COORD coordScreen = { 0, 0 };
   DWORD cCharsWritten;
   CONSOLE_SCREEN_BUFFER_INFO csbi;
   DWORD dwConSize;
   HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
   GetConsoleScreenBufferInfo(hConsole, &csbi);
   dwConSize = csbi.dwSize.X * csbi.dwSize.Y;
   FillConsoleOutputCharacter(hConsole, TEXT(' '), dwConSize, coordScreen, &cCharsWritten);
   GetConsoleScreenBufferInfo(hConsole, &csbi);
   FillConsoleOutputAttribute(hConsole, csbi.wAttributes, dwConSize, coordScreen, &cCharsWritten);
   SetConsoleCursorPosition(hConsole, coordScreen);
}

Thanks in advance.

I do understand what it does, but not how it does it.

You can look up each function here. Like GetConsoleScreenBufferInfo().

Also, Windows specific questions should go on this message board.
